CLAYTON MCPHERSON, OF BRIDGETON, NEW JERSEY.

DAIVIPER-OPERATING MECHANISNI.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application led January 24, 1905. Serial No. 242,535.

T0 all whom it may concern.-

Be it known that I, CLAYTON MoPHERsoN, a citizen of the United States, residing at Bridgeton, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Damper- Operating Mechanisms; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in automatic damper-operating devices.

The object of the invention is to provide a device by which a damper or other mechanism may be automatically actuated at a predetermined time.

A further object is to provide a device of this character which will be simple and inexpensive in construction and which may be applied to the winding mechanism of an alarmclock, so that when said device is released by the alarm mechanism a weight will be dropped, thereby opening the damper or actuating any other mechanism to which the weight maybe attached.

/Vith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described andk claimed.

In the accompanying drawings, Figure 1 is a side view of the device, showing the same applied to the winding mechanism of an alarm-clock and showing the parts set or in position to be released by the alarm mechanism of the clock. Fig. 2 is a similar view showing the parts in released position, and Fig. 3 is a front view cfa supporting-bracket and the parts supported thereby.

Referring more particularly to the drawings, 1 denotes a bracket in the upper portion of which is supported an alarm-clock 2. Said clock is held in place by means of a curved strap 3, which is bolted or otherwise secured to the bracket 1. On the bracket 1, below the clock 2, is arranged an outwardly-projecting arm or bar 4, on the outer end of which is pivotally mounted an upwardly-projecting lever 5. On the lower end-of this lever 5 is formed a laterally-projecting hook 6, with which is adapted to be engaged a loop or bail 7, to which is connected a weight 8. To the weight 8 is also connected the upper end of a flexible connection 9, which is adapted to pass over a guide-roller 10 and from thence extends to and is connected to the mechanism to be operated thereby. Said mechanism is here shown as a draft-damper 12 of a furnace.

The upper end of the lever 5 is adapted to be engaged by a hook 13, which is arranged on and secured to the winding-shaft 14 of an alarm mechanism controlled by the clock 2. /Vhen the alarm mechanism has been wound and set to the required time, the hook 13 is engaged with the lever 5, thereby supporting the weight 8. When the alarm mechanism is released by the clock, the hook 13 will be raised and disengaged from the lever 5, thus permitting the same to swing forwardly, which will cause-the weight 8 to slip 0H from the hook 6 and to drop, thus pulling upon the flexible connection 9, causing the damper 12 to be lifted or opened.

While l have shown and described the device as being connected with a damper to operate the same, it is obvious that the device may be applied to and adapted to automatically operate many other forms of mechanism.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus descibed my invention, what l claim as new, and desire to secure by Letters Patent, is-

In a device of the character described, the combination, with an alarm-clock, of a supporting-bracket, a lever mounted thereon, a hook formed on said lever, a weight, a loop or bail connected to said weight and supported by said hook, a latch-bar iixed on the alarmwinding shaft of said clock, and ada ted to engage said lever and normally ho d the IOO same in osition to support said weight until my hand in presence of two subscribing witreleased dy th;1 alaim melhansm, and a oord nesses. connecte wit sai weig t an 4passing over a pulley, whereby the falling of the same CLAYTON MOPHERSON 5 when released from said lever will aetuate Witnesses:
